is a colorless solid, however its color can vary from gray-brown to blue to almost black depending on it's grade. When fragmented, it has amorphous and crystalline aspect. It chemically consists of one calcium atom and two carbon atoms (CaC2) and is normally classified in standard granulometric ranges according to its use. Calcium carbide is produced in an electric arc furnace with a combination of limestone and carbon sources, such as petroleum coke and charcoal.
Uses of calcium carbide:
1. Resins: Used in the plastics industry, for resin production (PVC, MVC, etc.). 2. Siderurgy and Foundry:
Due to the strong desulfuration potential, it is used to remove sulfur from pig iron, steel, cast iron and nickel-iron. Calcium Carbide is also an excellent slag deoxidant agent, providing excellent results for secondary metallurgy during the tapping,and in the ladle furnace. In the Cubilot furnace (Cupola) it partially substitutes the metallurgical coke, allowing cast iron production with lower sulfur and operation with better alloy yield. 3. Metal Cutting and Welding:Due to its high flame temperature, the acetylene produced with calcium carbide is ideal for cutting and welding. 4. Soil:Used as a moisture detector due to its high hygroscopic property. 5. Production of Acetylene Black:Used in battery manufacturing.
